To all whom it may concern;

and 'arrangements of 'branching portion with a de 7 and 8 which as shown are arranged in reof Fig. 1'.

`I eit known that I, JOHN P. GINIVIN, a citizen. of the United States of America, and

a resident of the city of Seattle, in the county ofKing and State of Washington, have invented certain new and luseful Improvements in Ore-Cl ssifiers, of which the' following is-a speci cation.

Thepresent invention pertains to apparatus for disseminating metalliferous' slimcs or comminute'd ore and has particular reference 'to an improved fluid delivery system whereby current eliects of greater value can be produced.

The invention resides in certain novel P.features in the constructions, combinations arts as set forth, in the following description and defined in the appended claims,

In' the accompanying drawing` whereinl similar refe-rence numerals designate corre sponding"partsthroughout: Figli're 1 lis a verticalf'section of "a classifier embodying the features of my invention in such form as now preferred by me. Fig. 2 is a. plan in partial section on line 2-2 of Fig. 1. Fig. 3 is a horizontal section on line 3-3 of Fig. 1, and Fig.` Liis a vertical section on vline y The invention embraces a Vseparating chamber compising a transparent wall section, as a glass tube 1, and a tapering base section as 2, which asshown is connected with a gate valve 4 and provided with a stuffing box 3 wherein tube 1 is seated.

' Connected withthe upper portion of tube l'is a Y-shaped outlet euipped in its Gwhich is secured toa stem 6 seated in the wall of the outlet for adjustment ofthe dc. Hector to various. angularpositiox as may be desired in grading the materia -.carried into the outlet. p f

In conjunction withthe separating chamber I provideliiuid delivery `heads as 7, 7,

spective portions/of tube-1 and connected with a :pipe 9 leading from a supply of lwater under pressure. The heads 7 and 7 are 'identical in form, each comprising a cross 704 of piping extending transversely of tube 1, and a rotatable jet 71 provided with curved nozzles 72 carried by a hub 73 rotatably mounted on asuitable journal having communication with the cross and nozector or plateh the volume of flow in the outlet to direct the zle's. The arms f each cross are seatedil'i` suitable apertures in the wall of tube l and' one arm of each cross is connected with pi 9 throughs respective shutoii` valve 7 while the other arms are provided with suitable caps. The nozzles 72 are directed for outward delivery and provided with upwardly directed discharge orifices 72 While the arms of the crosses are provided with similar orifices as 70. Head 8 as will be observed extends beneath head 7 in proximity to the wall of tube 1 and appears in the form of a pipe which is connected through a shutoft` valve with pipe 9 and provided with discharge orifices 8 directed for discharge between thc path of the adjacent jet 71 and the wall of the chamber.

In o eration the jets 71, driven by the water ischarging from the ends of their nozzles, produce swirls or eddies which receive the delivery from the adjacent crosses 70, while the delivery from head 8 tends to maintain an upward How which receives the delivery from the outer endsofthe nozzles. The materials to be treated bein fed to the u per end of the chamber are t erefore subjected to disseminating effects'tend# ing to force them outwardlyand upwardly `and resulting in thorough cleansing of the heavierparticles as the gravitate to base 2 While the lighter partie es are caught by the currents and carried to outlet 5.

The effect of the currents upon the 'materials may be noted by inspection through the Wall of the tube and the valves 70 and 8Ol adjusted to re ulate the strength of the cur-l rents as foun desirable.

Deiiector 6 is adjusted in accordance with sus ended materials to the lower branch while permittingj of the remainder of the float beine carried along .in the upper branch, arid valv 4 is opened from time to time to Withdra tliematcrials accumulating in the base of the chamber.

Having thus described my invention what 'I claim as new, and desire to secure by Letf .ters Patentof the United States of America, 1s

1. An `ore-classifier comprising a separating chamber adapted to contain water, ro. tatably supported means arran ed to be normally submerged in said c amber, said means comprising a hub provided with Aa plurality of outwardly projecting nozzles,

formed intermediate their ends with spaced upwardly directed discharge orifices, and fiuid delivery means for directing water for discharge in an upward direction arranged below said lirst means for producingan upward How for' receiving discharce from the nozzles thereof.

2. An ore classifier' comprising` a separatv ing chamber adapted to contain water, a rotatable iluid delivery head provided with outwardly curved nozzles formed inter1nediate their ends with spaced upwardly directed discharge orifices, a hollow support 'for said 4delivery head extending` across said chamber and conununicating with said Huid delivery head, said support beingr formed with spaced discharge orifices, and means below said support for producing` an upward liow adjacent the wall ot' said chamber.

3. An ore classifier con'iprising a separating` chamber adapted to contain eter, a rctatable fluid delivery head arranged to be normally submerged and provided with out- Wardly curved nozzles arranged to direct dicharge of water in an outward direction and formed intermediate their ends with spaced upwardly directed discharge orifices, means arranged beneath said head to discharge water upwardly into vthe swirl produced upon` rotation of said head, and'ineans below said last means for producing an' u'pward flow adjacent the wall of said chamber.

e. Ancre classifier comprising a separat 'ing cl'lainher adapted to contain water, a,

plurality of' rotatable lluid delivery heads spaced one above another, n'ieans loclow each of said heads for directing water .for dis charge into the swirl produced ther diy, and means helow all ot said delivery heads 'for producing an upward flow adjacent the wall oi said clniniber.
